R448A refrigerant – an excellent replacement for R404A
R448A is an azeotropic mixture, which is classified as a non-flammable replacement refrigerant with a low GWP value. It was designed to serve as a replacement for R404A (and R22) in low and medium temperature systems, such as refrigeration solutions in supermarkets and vending machines connected to the power grid.
R448A refrigerant applications, use and replacement refrigerants
R448A is a suitable replacement gas for R404A systems. It can be used in new installations and as a direct replacement gas in existing systems. The GWP drops significantly from 3920 to 1386. In contexts where the evaporation temperature is low, cooling power drops 10–15% but efficiency is improved. Since there is some variation in capacity and power, this must always be considered with regard to handling, application and retrofitting.
R448A has been used in supermarket refrigeration systems and vending machines, for example.
R448A replacements or alternatives are: R407A, R407F, R442A
